3
4 1 Create master key in master database (set master key)
5
6 2 Create TDE certificate (encrypted by MK)
7
8 3 Backup the Certificate and private key, By encryption with a password ( did not do it in this case due to storage blog problems)
9
10 4 Choose DB to create the DEK ,Create database encryption key (DEK) with algorithm ( AES= 256) and encryption by certificate
11
12 5 Set encryption on for the database
13
14 -- 6 Create a new credential with the SAS token
15 CREATE CREDENTIAL [https://zagpebslab.blob.core.windows.net/sql-backups]

31 The backup was unable to be done from smss to azure ( the MI does not support encrypted DBs to be backed up from smss to azure)
32
33 We have unencrypted a database and backed it up from ssms to azure blob successfully
34
35
36 Conclusion: Can be done with and unencrypted DB but not with an Encrypted one>
